When a new engine is introduced that has 10 percent less displacement than the one it replaced, old-time gearheads start to worry. But this new 4.7 PowerTech V-8 was designed to outperform the old 5.2, and it really does. All you have to do is step on the pedal, and any doubts are whipped away as your neck muscles start to contract. The basics of the engine are a cast-iron block and a single camshaft on each of the aluminum heads. The new mill pumps out 235 bhp at 4,800 rpm and 295 lb-ft at 3,200 rpm and even meets California's LEV (Low Emissions Vehicle) standards. The combination of a 9.3:1 compression ratio, sequential multiport fuel injection with variable fuel-injection timing and coil-on-plug ignition makes this a peppy, durable mill.
